4 Claims.

This invention relates to window ventilators and has for an object to provide an improved construction of ventilator particularly adapted for use in casement windows or in windows which are hinged along a vertical line to swing inwardly and outwardly, the structure acting not. only to provide the desired ventilation but also presenting means for preventing the entrance of rain.

Another object of the invention is to provide ventilators for casement windows formed to lock the window in its open position.

A further object, more specifically, is to provide a ventilator for casement windows wherein the parts are foldable so that the ventilator may be stored in a small space when not in use, the structure being such that the ventilator may be quickly unfolded, placed in position and locked in position after having once been correctly positioned.

In the accompanying drawing- Fig. 1 is a horizontal sectional view through part of a wall and including a casement window, the same being shown in connection with a ventilator disclosing an embodiment of the invention;

Fig. 2 is a perspective view of the ventilator shown in Fig. 1;

Fig. 3 is a perspective view of the locking structure adapted to coact with the ventilator shown in Fig. 2;

Fig. 4 is a fragmentary sectional view through Fig. 2 on the lin ll4;

Fig. 5 is a fragmentary sectional view through Fig. l on the line 5-5;

Fig. 6 is a sectional view showing the upper part of the locking member shown in Fig. 3, interlocked with the upper part of the ventilator shown in Fig. 3; and

Fig. 7 is a view similar to Fig. 1 but showing the ventilator applied to a double casement window.

Referring to the drawing by numerals, I indicates a wall of any kind having a window opening 2 in which the window 3 is mounted. Window 3 is provided with a frame t having the usual hinged structure 5 and the usual actuating lever structure 6. Associated with the window frame 4 is a. window casing I which properly coacts and fits the window frame when the same is closed. It will be noted that the frame 4, casing 5 and associated parts are all of metal though these parts could be made from wood without departing from the spirit of the invention, as all of the parts just described are old and well known and form no part of the present invention except in combination.

Associated with the casing and the frame 4 is a ventilator 8 which acts in the double capacity of a ventilator and as means for locking the window open. From Fig. 2 it will be noted that there is provided a Vertical panel 9 and top and bottom panels Ill and II, said top and bottom panels being hinged respectively at l2 and i3 to the vertical panel 9. Panel 9 is provided with any number of louvers l4 so that air may freely enter but rain cannot enter. Along the outside edge of panel 9 is provided a flange structure l5 which functions as shown in Fig. 1 so as to overlap the flange l'B'of frame 4. It will be observed that flange I5 merges into a channel'or groove which accommodates the edge portion of flange 15 of frame i. This provides a tight interlocking connection whereby the parts will not accidentally become disengaged. Along the inside edge a flange ll is provided which has a longitudinal groove for receiving the flange l8 of the casing l. The top panel II] is also provided with a grooved, flanged member [9, the groove facing downwardly and being adapted to straddle the upstanding flange 20 of casing l, as shown in Fig. 4. The inner edge of the panel In is provided with an upstanding straight flange 2| which fits flatwise against the top flange 22 of easing 1. It will be noted that as the window is pivotally mounted near one vertical edge that it must necessarily swing outwardly, as shown in Fig, l and to accommodate this angle the top and bottom panels ii] and H are tapered.

The top panel I5] is preferably solid throughout so as not to allow any moisture to enter, but the bottom panel I I may be provided with apertures 23. This bottom panel H may be provided with an inner depending flange 24 and an outer depending flange 25, as shown in Figs. 2 and 5. These panels merely bear against the frame 4 and casing 1, respectively, flange 24 being fitted interiorly of part of the frame so as to prevent any outward swinging movement of the window, which outward movement is also prevented by the flanged member I9. The panels ill and ll are each formed with an in'turned hook member 26. Hook members 21 on the ends respectively of a locking bar 28 are adapted to interlock with the hook members 2t, as shown at the right in Fig. 6. In addition, the locking bar 28 is provided with an inturned flange 29 and an outturned flange 29. As shown in Fig. 1 this flanged arrangement is shown as overlapping part of the,

frame 4 and part of the casing 1. This is to prevent the entrance of water at this point. It will be observed that the various parts of the ventilator are connected together in some manner and also that they are interlocked in some manner either with the casing 1 Or the frame 4 whereby the window is locked against accidental movement, and also means are provided for allowing air to freely circulate without allowing rain to enter.

In Fig. 7 anarrangement is shown whereby the same ventilator as is illustrated in Fig. 2 is applied to a double casement window. Aside from the fact that it is a double casement window the structure is identical to that shown in Fig. 1.

I claim:

1. A ventilator for casement windows, comprising a base panel adapted to be mounted vertically when in use, said base panel being provided with means interlocking with one edge of the window with which it is associated and part of the window casing with which it is associated, a tapering top panel hingedly connected at its large end to the base panel, a tapering bottom panel hingedly connected at its large end to said base panel, means on the respective top and bottom panels for interlocking with the top and bottom edges of said window, means on the respective top and bottom panels for interlocking respectively with the top and bottom portions of the window casing, and a locking bar slidingly connected with the small end of the respective top and bottom panels, said sliding bar being provided with a pair of flanges adapted to overlap part of said casing and part of said window frame so that the locking bar will act in the double capacity of locking means and means for closing the space between the window and the casing near the hinged portion of the Window.

2. A ventilator for hinged or casement windows comprising a base panel having louvers and grooved flanges on the respective edges, said flanges facing in opposite directions, a top panel hinged at the upper end to said base panel, a bottom panel hinged at the lower edge of said base panel, each of the last mentioned panels being provided with a flange on each side, and a looking lbar formed to interlock with the free end of said top and bottom panels.

3. A ventilator for windows which are hingedly mounted along a vertical line, comprising tapering top and bottom panels, a vertical base panel hingedly connected on'its respective ends to the top and bottom panels, said top and bottom panels at their free ends being turned over to form hook shaped portions, and a locking bar having inwardly and outwardly extending flanges at their respective edges, and turned over ends constituting hook portions adapted to slidingly interlock with the hook portions on said top and bottom panels.

4. A ventilator comprising a substantially rectangular base having an outwardly facing grooved portion along one edge and an inwardly facing grooved portion along the opposite edge, top panel hingedly connected at the upper end to said base panel, said top panel having a downwardly facing grooved flange along one edge and an upwardly facing straight flange along the upper edge, and a bottom panel hinged at one end to the lower end of said base panel, said bottom panel having a straight depending flange along each of said edges.
